That others may understand the construction and operation of my machine, I will'particularly describe it and the ma'nner of using it.,

A is the main frame of my machine, mounted upon the tops of the two hollowpillars B B, which are secured at their bases to the bed-plate C." These parts are constructed of cast iron, as is common with similar machinery. The main frame A is composed of two heavy plates joined atone edge and placed at right angles to each other, with angle-braces between, as is fully shown in figs. 2 and 3.- The horizontal partof the frame A rests upon the top of the pillars B, and is secured there by bolts, and the vertical part forms the face upon which are secured the drill-stocks, as .seen in figs. 1 and 2. Upon the front of each pillar B is a flat face, D, which is planed true and with projecting parallel edges. I Upon these faces move the brackets E, which support and raise the work to the drills. The bracket E overlaps at its sides the projecting edges of the plane D,-which, as is common in similar structures, are made in the form of a. dove-tail. From the back projects the lug F, which may be cast solid with the bracket, or may be secured by bolts. Through this lug is a feinalesrew, adapted to the feeding-screw G, which is located within the pillar B. By the revolution of the screw G, the bracket is raised or depressed. The upper edge of the bracket E is made true and at right angles to its rear edge, so that .it projects at right angles to-the axes of the drill-stocks when in place. The slot through the face-IL, through which the lug F projects into the cavity of the pillar, is suificient ly long to permit .the bracket to drop out of connection with the screw G, 2'. 2., when the lug F rests upon the bottom of-the said slot, the lower end f th screw G will be a little above the upper surface'of said lug, and in this way one'oi' the brackets may, if desired,

be thrown out of service, and the power required to drive the machine decreased by the amount required to raise or lower one bracket. In the drawing the artist has shown the bracket as owered, in red, but lower down than they 'could go without detaching the lug F. t

The crews G G are attached at their upper ends to the wheels H H, through which the said screws are operated. The lower side or hub of the wheel H rests upon the upper surface'of the base-plate of the frame A. The shaft of the screw. is turned true and fits the orifice through which it passes; andno other bearing is required, as the pendent end is kept in position by the lugF. Washers or bushing may be introduced if it is thought desirable. p i l The feeding-screws are operated by the geared wheels H which in turn are actuated by pinions I I upon the counter-shaft J. Motion is communicated from the prime mover K, through a reduction series composed of the pulleys L M and'the geared wheel and pinionN O, the wheel N being upon the end ofthe counter shaft J, and the pulley M and pinion 0 upon the shaft P. The shafts J, K; and P are located above the base- .esnsr plate of the frame A, and have their hearings in the end brace-plates'of the same,as is clearly shown in figs. 2 and 3. 4 j

The wheel N is loose upon the shaft J, and is providedwith a clutch and clutch-pin, by which the shaft J may be at any time thrown in or out of connection to start or stop the feeding-screws G. The clutch is operated by the rod Ronda-rank S, the shaft. of which projects through to the front of the frame A, and is there controlled and operated by the lever T, which is at all times convenient to the hand of the'attendant. The pinion U is secured upon the shaft J, at about its centre of length, and the gear-wheel V, whose shaft projects through the faceplate of the frame A, and is connected with andoperated by the hand-wheel W on its front end, serves to run the shaft J and the feeding-screws G G up'or down, to bring the work tothe drills or relieve them when the holes are completed. The stop-lover I and hand-wheel ,W are both in front of the frame A, and convenient to the hand of the attendant. I V

The drill-stocks do a a a a a a a a a a a a a a a are mounted in hearings or box-es b b, secured to the face of the frame A, asshown in fig. 1. At the upper end of each drill-stock a is a small bevel pinion, c, which gears with a corresponding bevel driver, d, upon the shaft K, upon the end which are the main fast-and-loose pulleys e j I The boxes 6 may be attached in a variety of ways, but I prefer to attach them so that they may be adjustable sideways. I have, however, constructed my machine, sometimes with the boxes formed at definite intervals in a continuous bar, which I afterwards attached to the face-plate A. It is desirable to have the drill-stocks adjustable sideways, so that the spacing of the drills may be changed if necessary. I have therefore sometimes passed the clamping-bolts through slots in the face of the frame' A, the bolt-heads then projecting on thc rear side of said plate, but I deem itpreforahle to cast the frame A. with two undercut channels along its face, one near the upper edge andone near the lower edge, as shown in fig. 6 at g. In these channels the heads of the clampingbolts are placed, and the adjustment of, the boxes then is limited only by the length of the frame A. The driving bevels d d are similarly adjustable by means of set-screws, which secure them to the shaft K, and permit them to be moved thereon at will. Theboxes a may be secured with two clamping-bolts, as in fig. 5, or with one,

as in fig. 7, the latter arrangement permitting them and the drill-stocks to be brought nearer together than could be the case were two bolts to be used. In fi' 7' the artist has represented the clamping-bolt as beingtoo far .from the drill-stock. is If one bolt onlv is used it should be inserted as near to the surface of the stock as ossiblc.

The drilLstoc-ks a are made tubular through the whole or a great part of their length, as shownin figs. 2 and 8, and at the lower end is a clamping device, so that I am' enubled to use for my drills steel rods m of con v'enient and proper size and length. These rods are flattened at one end and the drill-points formed of proper size, and the rod is then inser ed and clamped in the stock. By this arrangement I am enabled to tree a long drill-rod without having a greater length of it below the stock than may be desirable. I am also enabled to adjust at any time the drills, so that they. shall all project a uniform distance, and thus all commence and finish their work together. Less labor in preparing and fitting the drills is required than would be the case if any other system should be adopted. The lower ends of the drill-stocks are fitted as follows, a description ofone being applicable to all: The bore of the stock is enlarged at the lower end, forming a. conical recess, as at h,

fig. 8, and below this again the sides are parallel, and provided with a female screw-thread, as at i, fig. 8. Into the conical part b I fit a stecl plug, it, of corresponding conical form, and below this plug, the screw-follower n. Both plug and follower are pierced with. a hole corresponding with the bore of the stock a, through which the drill-rod mis to pass, and the plug, in. addition to the hole drilled through its centre, is sawed transversely in two directions, so as to separate the cone, from point to base, into three or four pieces. The efi'ect of this is,- that as the follower n is screwed up into the stock, the plug is is forced upon the conical sides of h, and the removal of metal in sawing through the plug pcrmitsthe several parts to draw nearer together as they ascend, and if the drill-rod is in place, they are forced upon it, with the effect of clamping it firmly in position. Several small holes are drilled into the edge of the follower for the convenient application of a lever to operate it.

A trough, o, is used to hold the work being drilled: This trough is seen in elevation in fig. 4, in plan. in fig. 3, and in longitudinal and cross-section in figs. land 2. It is constructed of cast iron, and for convenience it is cast double'so that it may be revers'ed, as shown in figs. 1 and 2. The edges are made high enough to permit the work being operated upon to be immersed in water, oil, or some other anti-friction and cooling liquid. A hole'stopped with a plug forms a means of discharging the fluid contents of the trough when desired. Across the bottom are transverse ribs of slight, elevation, and usually I form a ledge along the side next-the wall, or two longitudinal ribs nearer the centre. Infinishing this trough, the outer sides are planed true and parallel with each other, and the surfaces of the transverse ribs are planed off so as to be of equal height; the work then rests upon them equally, and the drills penetrate entirely through without cutting the bottom of the trough. I'n fig. 1 the artist has not disposed these ribs at proper distances, as they should be spaced to correspond with the distances of the drills from each other. In operation, the trough o rests upon the brackets E,

' and rises and falls with them, carrying the work to or from the drills.

In drilling finger-bars, a pattern-plate, p, of hardened steel is used. This pattern-plate 9) is of precisely the size and form of the finished finger-bar, and is provided with holes corresponding in size and position with those which are required to be drilled in thc finger-bar. It is also provided with two screw-clamps .q g, which are attached rigidly to the pattern-plate and embrace the cdgesof the finger-bar. In the finger-bar pattern-plate represented in fight), there are the necessary holes for fourteenguard-fingcrs, four stay-plates to keep-the cutter-bar confined in its guide-way, and the required holes for the attachment to the inner and outer shoes. Of these the holes for the guard-fingers are drilled at two operations, fourteen each time, the other holes being drilled at a subsequent operation. My drilling machine is also applicable and equally usefulin drilling the necessary holes in the nail or brac -rods which connect the guard-fingers in front of the finger-bar, and in I drillingthe holes in the guard-fingers themselves, so that these parts areull periectly interchangeable. and may be assembled or parts replaced \vithout'any trouble in selecting or fittinglfl A pattern-bar is used in connection with thc'nail-rod and a peculiar holder in drilling the required holes in the guard-fingers. End and side views of the guard-finger holders are seen in figs. 4 and 10, and fig.. 11 shows, in vertical longitudinal section, one of the completed guard-fingers with .the relative position and size of 'the holes. The finger-holder r is a blocltof cast iron, having on its upper side a recess which corresponds exactly \i'ith the under surface of the guardfingert The bridge t permits the employment o f'ja vertical bindingscrew which presses the guard-finger into the recess referred to and holds it there securely. A pattern-plate, u. of hardened steel, corresponding in form to the indentations of the upper side of the guard-finger,-is placed over said finger, and the binding-screw retains it in placeatthe same time that it so secures the guard-finger. The rivet for securing the nail-rod is smaller than those which secure the finger and bar together, and a smaller drillis therefore employed. The finger-holders r are of such length' as will fit easily yet snugly within the sides of the trough when the holder is transverse thereto, as shown in fig. 4'; and in using my machine for drilling fingers I remove every third drill, and replace each alternate of the remaiiiing ones with a smaller drill suitable in size for the nail-rod rivets this arrangement is shown in iig. 4. The finger-holders are now placed in the trough, so disposed that they will come under each fourth drill-stock properly. The trough is now raised by the brackets until one set of holes is drilled. The trough is then brought forward or backward until the next set come under the drills; when these in turn are completed, the trough is shoved endways until thc'fingers are beneath the smaller drill, when the hole for the nail-rod rivet is drilled. p

The drills are all adjusted veryreudily and expeditiously as follows: They are all raised up and held at the highest point t the trough is then set on its edge upon the brackets and brought up so that the drills, when let down and their points resting thereon, shall be projected from their stocks the proper distance. The sides of the trough being planed true and parallchfurnish'a true surface for this adjustment. When. very drill has been brought to thissurface it is clamped in the mono er described, and they then-all commence and finish their work at the same moment. It is sometimosdesirahlc to use only one bracket and drill, and at such times it will beconsider ed advantageous to drop one bracket below the i'ceding-scrcw,as heretofore set forth.

In the-operation of drilling either finger-bars or guard-fingers it is advantageous to have two attendants, one to operate and manage the machine: the other to discharge completed work and to prepare new. This preparation consists of the rcplaeing bla'nkfinger-hars in the pattern-plate clnmpand in displacing and replacing blank fingers in the holders, so that thefoperation of drilling may go on almost continuously and uninterruptedly Having described my inyen tiomtw hatl claim as new, an'd de'si rc to secure by Letters Patent, is-- The main frame A, constructed as described, and'monnted'upon'the hollow pillars B B and bedplate C, as and for the purpose set forth. f i I v The crank S, connecting clutch-rod R, and lever'T in combination, the two former being behind and the latterin front of the frame, as and for the purpose shown and described.
